CE Oriented Product Variant Design System Research

To the questions that low rate of knowledge reuse,long development cycle and high cost in serial design patterns,we researched CE oriented product variant design technology.Establishing concurred design pattern which centered on products,structureing collaborative working environment with client/server/workstation network system structure,and managing integrated all relevant information about products and process related information in PDM system,realized multi-user rapid concurrent design.Taking crane bridge as example,and results show that arrived optimal cost-effective combination design.
